Construction building material 25CrMoS4 alloy steel plate hardness yield strength
The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team. In the future service process, the after-sales service adopts regular return visit for customers. Timely understand the customer's satisfaction with our products, and solve the user's problems at any time.
25CrMoS4 alloy steel plate hardness smelting methodThe smelting process of electric furnace + external refining and vacuum degassing can be used for secondary electroslag remelting smelting. The steel plate should be intrinsically fine-grained steel, belonging to the 1.25Cr-0.5Mo series of pearlite heat-resistant steel, with good high-temperature strength, oxidation resistance, and sulfide corrosion resistance below 500°C. It is widely used in coal chemical industry and petroleum High temperature and high pressure vessel installation in the chemical industry.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. 25CrMoS4 alloy steel plate hardness, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
Spring steel, as we can clearly know from its name, is one of the main materials used to make springs and special alloy steel for other elastic components. 25CrMoS4 alloy steel plate hardness, Spring steel has good comprehensive properties, it has heat resistance, low temperature resistance, oxidation resistance, corrosion resistance and so on advantages. Compared with alloy spring steel, carbon spring steel has less advantages, but its price is cheaper, and the source of raw materials is convenient. The disadvantage of carbon spring steel is that the elastic limit is low and it is easy to lose elasticity after repeated deformation.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products 25CrMoS4 alloy steel plate hardness and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.
